Detailed Instructions for Using the Application Alignment Tracking

  1. Initial Setup:
    • First, upload your route file in KML format to the application.
    • You can create a KML file using various programs, but Google Maps is the easiest option.
    • Watch this short video to learn how to create a KML file: Creating a KML File.
    • KML is a text file format containing the waypoints of your route.
  2. Transfer the File:
    • Transfer the KML file to your phone's storage.
    • Tap the three dots in the upper-right corner of the app.
  3. Select Working Mode:
    • Choose between 2D or 3D mode.
    • Either mode will work initially, with calculations being the same. Note that 2D mode is recommended for routes up to 40 km (130k ft), while 3D mode has no such limitation.
    • Detailed descriptions of each mode's properties will be provide

      4. Location Detection:

    • If your phone's location services are enabled, the app will display your current latitude and longitude on the 3rd and 4th lines.
    • For smaller route files (up to a few thousand points), the app will quickly convert your location coordinates to positions relative to the route.

      5. Route and Offset Information:

    • STA 1+431.04: This shows the cumulative length of the route from the starting point to your location's projection on the route. If projection onto a line segment is not possible, symbols will be displayed ???

    • Of. -25.42: This indicates the shortest distance to the route from your location (negative means left of the route, positive means right).


Station - Offset


      6. Dynamic Updates:

    • The app updates your position relative to the route every 0.5 seconds (2 Hz).
    • Even when moving, it will continuously calculate your stationing and offset.

      7. Stationing and Offset System:

    • This system is useful for tracking your progress on the route.
    • For example, calculating the distance between two geographic points is complex, but finding the difference between their station numbers is straightforward.
    • Station numbers use a thousand-separator (+), e.g., 1+431.04 is the same as 1431.04.
    • Offsets to the left of the route are negative, and to the right are positive, with color coding (red for left, green for right).


Survey points Import/export of survey points

       8. Elevation:

    • The last line displays the elevation above sea level, which is not recalculated.

       9. Adding Labels:

    • You can save Points of Interest (POI) while traveling.
    • Pressing "Add Label" creates a TXT file named after the loaded KML file plus the timestamp.
    • The file template is:
Station, Offset, Elevation, Description, Lat, Lon, Time
    • Example:

1430.55,-25.40,167.80,ConcretePoles,52.0715937,23.726064,Thu May 09 17:14:30 GMT+03:00 2024

     10. Data Security:

    • In case of an app crash, the point file is not lost. It is created and updated with each point addition.
    • The file can be found in the "Downloads" folder.


Reference Sta.- Station of previous point Alt.- Elevation of previous point % - percentage of route traveled 	those. still 28.87% left @ - point number # - segment number 	(total amount) Δ - distance to the previous point
Sta 2+080.66 , then entering the value -1000 will change the value to Sta 1+080.66 ( a negative picket is allowed , i.e. 2+080 entering Starting Station -3000 = Sta -0+920.00

     11. Additional Features:

    • Starting Station: Adjust the starting station value to get a specific station number at your location.
    • Share File: Share the created TXT file.
    • M to ft: Toggle between meters and feet (active until the first point is added).
    • Select KML file 2D: Best for routes within a 40km x 40km area due to projection limitations. Calculations are made in a plane, elev. 0
    • Select KML file 3D: Shows inclined distance, useful for routes with varying elevations.
